Sir Didymus and Ambrosius

Sir Didymus and Ambrosius are the two tetartagonists, respectively, from "Labyrinth". They are the last two companions Sarah meets. Sir Didymus is a fox with an eyepatch and talks like a knight. Ambrosius is a cowardly sheepdog who acts as Didymus' horse. Sir Didymus was operated by Dave Goelz and David Barclay, and was voiced by David Shaughnessy, and Ambrosius was performed by Steve Whitmire and Kevin Clash and voiced by Percy Edwards.
